Short Bio:

I love data.

There’s nothing more exciting than using the information we have all around us to understand more about how people interact with the world through their financial products.

As head of the UK Data Lab at Capital One I lead a cross-functional team that is changing the way we do business. We use the latest distributed computing technologies and operate across many billions of customer transactions. The models and data products that my team build unlock big opportunities for the business and help UK consumers save money and reduce friction in their financial lives.

Capital One is a founder led company on a mission to change banking for good by bringing simplicity and humanity to all that we do. We’re a business dedicated to helping our customers succeed through digital solutions. We pride ourselves on attracting and developing the best talent. Our people are the key to our success and ultimately what makes Capital One the number one Great Place to Work in the UK for the past 3 years!

I'm interested in connecting with other Data Scientists, Statisticians or Data Visualisers to discuss advances in the fields.

I'm also on the look-out for ambitious, talented people to join my team as we build out our capabilities, using data to Change Banking for Good!
